“Come and Get It” singer Selena Gomez entered rehab to treat anxiety and depression, Us Weekly reported Wednesday. The former Disney star canceled the 34 remaining dates on her Revival world tour to treat her mental illness. Gomez also suffers from the chronic autoimmune disease lupus.

“Selena is dealing with lupus, but this break is to focus on her mental health,” a source told Us Weekly. “She can go to a very dark place.”

The name of the rehab facility was not released, but an insider said it was just outside of Nashville. It’s a “private and quiet place,” but “super intense.”

Gomez’s fans worried about the singer after some people noticed a dramatic weight loss. They took to Twitter the days before her rehab stay to wish her well.

It’s not the first time Gomez, 24, went to rehab. The singer, who famously dated Justin Bieber, went in 2014, a year after she was diagnosed with lupus and put a hold on her career. “She was supposed to be recording, but she hasn't told anyone when she’ll be back in studio,” an insider told Us Weekly at the time.

Gomez has been silent on social media for weeks. Her last post was more than eight weeks ago. It’s a surprising departure considering she’s one of the most followed people on Instagram with over 100 million followers. An image from 15 weeks ago garnered nearly 4 million likes.

The 24-year-old has not released a statement about her rehab stay. She openly talked about her diagnosis for one of the first times during an April interview with GQ magazine. “First off, this is something that everyone always wants to fixate on. I got diagnosed with lupus,” she said. “I needed time to just be okay.”
